Excusing yourself

I’m sorry 

You can use this expression after you have in some fashion offended an individual (by stepping on his or her toes, bumping into the person, or saying the wrong thing). “I’m sorry” can be used for the most trivial or the most serious offense. Your tone and expression will indicate the depth and sincerity of your feeling.

Excuse me

You can use the expression when you approach a stranger for assistance; to warn people that might inconvenience them (when fighting your way through a crowd, for example); or after you have made some minor blunder that does not necessarily offended an individual (such as burping). If you pronounce the phrase as a question (i.e., you use rising intonation), then it means “please, repeat.”

Pardon me?

Use this expression when you don’t understand what someone just said.

Basic Sentence Structure

Basic sentence structure simply means the basic order of the words in a sentence.

Ed	kisses	Mary.
S

"Ed" is the subject of the sentence. The subject usually comes first in the sentence.

Ed	kisses	Mary.
	V

The verb, in this case, "kisses," indicates the action of the sentence and it usually comes in second place.

Ed	kisses	Mary.
		O

And here’s who or what the action is happening to – the object, “Mary.”  It usually comes after the verb, in third place.

Mary	slaps	Ed.
S	V	O

The sentence structure in English tells us who is doing what to whom. In this sentence, Mary is the subject, "slaps" is the verb, and "Ed" is the object.
